Application filed June 17, 1922. |`Serial No. 569,018.

To all whom it may concern.'

'Beit known that l. WALTER D. BRYSON, a citizen of the United States,and a resident of llidley Park, county of Delaware, and State'ofPennsylvania, haveinvented certain new Vand useful'lmprovementsinFolding Boxes, of which the following is a specification, referencebeing had to the accompanying drawing.

My invention relates to foldable boxes which may be used for shippingory storage purposes.

A principal object of my invention is to provide a box which may beconstructed from a unitary. piece of suitable material such as manilachip fibre board, the blank being made by a suitable die whereby theparts may be folded into proper relation to form the completed box.

A further objecty of my invention is to provide a folded box ofsuflicient rigidity in which articles of considerable weight, such asshoes. may be shipped in individual boxes by express or parcels post andthe box and contents be preserved from damage or breakage in the roughhandling to which they may be subjected.

A further object of my invention is to provide a box which upon beingfolded may be secured into closed position by the engagementY of partsintegral with the blank.

A further object of my invention is to provide a box from which thecontents thereof may not be removed without mutilation of the box.

The invention further includes all of the various objects and novelfeatures of construction and arrangement hereinafter more definitelyspecified and described.

In the accompanying drawings. in which like numeralsffdesignate likeparts in the different figures, Figure 1 is a perspective view of thebox with one end open; Fig. 2 is a longitudinal sectional view of thebox with one end being shown as disposed at the beginning of the closingoperation; Fig. 3 is a view of one end of the box` partly inlongitudinal section. showing the dis position of the closure parts atan. intermediate stage of the closing operation; Fig. 4 is a transversesection on the line 4-4 of Fig. 2; and Fig. 5 is a plan view of theblank before the saine is folded. the points at which the blank is cutentirely through being indicated in full lines and those at which it isscored to facilitate the foldin pperation being indicated in dot anddaslgi mes.

ln the drawings, 1 is the bottom of the box, 2 the top and 3 and 4 thesides thereof;

a stitching lap 5 is adapted to be stitchedor fastened by staples 6along the upper edge of the side 4.

The box is constructed from a blank of suitable material and I havefound that manila chip fibre board with jute lining is a verysatisfactory material, supplying desired rigidity and strength for thepurposes of my invention. The blank is formed from a unit of the fibreboard or other suitable material by a suitable die, the shape of theblank being shown in Fig. 5. y

ln the construction ,of the box from the blank the latter is firstfolded at the lines 7. 8 and 9 which have been scored in the blank bythe die and then the stitching lap 5 is secured to the. side 4 by thestaples 6 or by any other suitable means, thereby forming a tube openat. both ends. The portions 1() and 11 at the ends of the top 2 arebendable along the scored lines 12 and 1 3 and form parts of the meansfor closing the ends of the tube. The die'also forms tongues 14 in theend flaps 10 and 11 which are bendable along the scored lines 15.rlongues 16 are similarlyl formed in the sector shaped corner pieces 17and tabs 18 provided with ears 19 are formed on the end flaps Q0.

The closures for one end of the tube to form the completed box areassembled as follows. it being understood that the other end of the tubeis closed in a like manner. The corner pie-es 17 are bent along thescored lines 21 and are inserted slightly within the tube. as shown inFig. 3, and then the end fiap 10 is brought into its closed position asalso shown in Fig. 8; the ears 15?-19 are then bent about the scoredlines Q2 so as to substantially lie flat on the tab 18 and the tongues16 are bent slightly inwardly on the scored lines 23; the tongue 14 isbent inwardly of the tube to permit the insertion of the lock tongue 18into the slot thus formed. The corner pieces 17 are then inserted intothe tube into their final position as shown in Figs. 2 and 4 Whereuponthe ends of the tongues 16 which no longer lie in the plane of thecorner pieces,

lill@ but, owing to the resiliency of the material have sprung awaytherefrom and toward the interior of the box, will formcatches'retarding the pulling out of the end flaps 20, the ends of thetongues 16 contacting with the inner surface of the end flaps 10. Thewings or ears 19 of the tongue 18 after insertion through the slot asabove described will, owing to the resilienc of the material spring backsubstantial .y into the `plane of the tab 18 thereby preventing thepulling open of the end flap 2() without destroying the box, the tongue14 also by reason of its frictional contact with the tab 22 assisting inpreventing the pulling open of the end 20.

It will be seen that after the ends of the tube have been closed in themanner aforesaid a container is formed which cannot be opened without soniutilating the box that it cannot again be usedin the original mannerand that if used at all supplementary fastening means would be necessaryin order to keep the ends securely closed. By providing closure means ofthis type it will be seen that an effectual safeguard is affordedagainst surreptitious removal of the contents of the box inasmuch as theappearance of the box after it has once been opened would disclose thatit had been tampered with.

While I have herein described with particularity a preferred embodimentof my invention, I do not thereby desire or intend to limit myself tothe precise details of construction and arrangement of parts as the samemay be modified and varied in minor particulars from those shown in thedrawings and herein described without departing from the spirit andscope of the invention as defined in the appended claims.

Havingl thus described my invention, I claim and desire to protect byLetters Patent of the United States:

1. A box formed from a unitary blank of bendable material and comprisinga top, a bottom and two sides, end members, provided with slots,extending from the top and adapted to be bent to close the end openings,bendable end members extending from the bottom, each comprising acentral portion having a tab with bendable Wings adapted to engage saidslots against withdrawal, bendable corner portions, having tonguesformed therein, on each side of said central portion and adaptedto slideWithin the box, said tongues being adapted to contaat with the interiorof the box and provide resistance against withdrawal of said cornerportions.

2. A box formed from a unitary blank of fibrous material` said blankbeing weakened along the lines of bending and comprising a top, bottoniand two sides, bendable end members, provided with slots, ex- -tendingfrom the top and adapted to close the end openings, bendable cnd membersextending from the bottom, each comprising a central portion having atab with bendable ears adapted to pass through said slots and be heldagainst withdrawal therefrom. bendable sector-shaped portions, havingtongues formed therein, on each side of said central portions andadapted to be inserted within the box, said tongues being adapted tocontact against the interior surface of said first mentioned endmembers.

3. A box formed from a unitary blank of fibrous material, said blankbeing scored along the lines of bending, and comprising a top, a bottomand two sides, a flap carried by the top adapted to be secured to one ofthe sides, end members, provided with slots, extending from the top andadapted to be bent to close the end openings, bendable end membersextending from the bottom, each Comprising a central portion having atab with bendable ears adapted to pass through said slots and be heldagainst withdrawal therefrom, bendable sector shaped portions, havingtongues formed therein, on each side of said central portions andadapted to slide within the box.I said tongues being adapted to contactagainst the interior surface of said first mentioned end members.

In witness whereof, I have hereunto set my hand this 16th day of June,A. D. 1922.
